Application
Cobalt(II) nitrate hexahydrate, has been widely used for the synthesis of Cobalt oxide nanoparticles and cobalt containing compounds. For Example:Cobalt(II) nitrate hexahydrate is used to synthesize cobalt-cobalt oxide/N-doped carbon hybrids, which are then used as hydrogen evolution reaction (HER) or superior oxygen evolution reaction (OER) catalysts in water splitting.
It has also been used as a primary precursor material in the synthesis of Co3O4 nanocrystals in various shapes such as nanosheets, nanocubes, and nanobelts as a catalyst for methane combustion.
Furthermore, the reaction of Cobalt(II) nitrate hexahydrate with Nickel(II) nitrate hexahydrate produces Nickel-cobalt layered double hydroxide nanosheets in presence of methanol and CTAB, which is used as a high-performance electrocatalyst for oxygen evolution.
In addition, Cobalt(II) nitrate hexahydrate precursor powder is calcined to produce Co3O4 nanotubes using the template synthesis method. The Co3O4 nano-tubes, nanorods, and nanoparticles that have been created are used in gas sensing systems and as anode materials for Li-ion batteries
Cobalt hydroxide and layered double hydroxides (CH@LDH) have been synthesized using Cobalt(II)nitrate hexahydrate as a sulfur host for lithium–sulfur batteries.
It is well studied that, Cobalt(II) nitrate hexahydrate is used as a heterogeneous catalyst Co/SiO2 with Silica support, for Fischer−Tropsch Synthesis.
Cobalt(II) Nitrate Hexahydrate is also used as a catalyst for the synthesis of 5-Carboxanilide-dihydropyrimidinone derivatives by the condensation reaction of acetoacetanilide, aldehyde and urea/thiourea.
